To create an SC APS IMA or MLPPP bundle

Purpose

Perform this procedure to create an APS bundle using IMA or MLPPP links on one NE. Consider the following when you add a DS0 channel that is a member of an APS group to an APS bundle:

An APS channel can be a member of an APS bundle only, not of an IMA or multilink PPP bundle.
All members of a working bundle must belong to a working channel of the same APS group.
All members of a protection bundle must belong to a protection channel of the same APS group.
You must create the working bundle before you can add an APS member to the APS bundle. If the member has a protection port, you must create the protection bundle before you can add the member to the APS bundle.
You cannot delete the working port member of an APS bundle until you remove the member from the APS bundle.

The rules for adding a member to a bundle that is part of an APS bundle also apply to adding a member to a non-APS protected multilink bundle. See To create an MLPPP bundle and To create an IMA group bundle for more information.

The following restrictions apply when adding a DS0 channel to an IMA bundle:

The Clock Source parameter must be set to Node Timed.
The encapsulation type of the DS0 channel must be ATM.

The following restrictions apply when adding a DS0 channel to a PPP bundle:

All time slots on the DS0 channel must be selected.
The encapsulation type of the DS0 channel must be IPCP.

Steps


1	On the equipment tree, right-click on the device where you want to configure an APS bundle and select Properties. The Network Element (Edit) form opens with the General tab displayed.
2	On the Network Element (Edit) form navigation tree, expand the Shelf icon.
3	Right-click on the APS Bundles object and choose Create Bundle. The APS Bundle Display form opens.
4	Configure the Bundle ID and Description parameters and click Next.
5	Set the Bundle Type parameter to IMA Group or PPP and configure the applicable parameters.
6	Click Finish and then click Close. The APS Bundle Display form closes.
7	If the Bundle Type parameter is set to PPP in Step 5 , configure the MLPPP bundle for multiclass service transmission. Note: Consider the following when you configure MC MLPPP. MC MLPPP is supported only on channelized ASAP MDAs on a 7705 SAR or 7750 SR. You must configure MC MLPPP before you add bundle members. MC MLPPP is configured on the main APS bundle and the parameters are propagated to the working and protection bundles. You can only apply QoS profiles to an MC MLPPP bundle when the Class Count parameter is set to 4. Use the following steps: Right-click on the SC APS Bundle object in the navigation tree and choose Properties. The APS Bundles (Edit) form opens. Click on the MLPPP tab and configure the required parameters. Select a QoS profile in the MLPPP Ingress QoS Profile or MLPPP Egress QoS Profile panel, if required.
8	Click on the States tab and configure the Administrative State parameter. Note: You must configure the End Point ID parameter on the APS PPP group before you set the Administrative State parameter to Up on the working and protection bundles.
9	Save your changes.
10	Configure the APS working and protection bundles: Note: You must create the working bundle before you create the protection bundle. Use the following steps: Right-click on the SC APS Bundle icon in the navigation tree and choose Create APS Working Bundle. The Create APS Working/Protecting Bundle form opens. Configure the required parameters and click Next to view the configured bundle parameters. Click Finish and then click Close. The Create APS Working/Protecting Bundle form closes. Right-click on the SC APS Bundle icon in the navigation tree and choose Create APS Protection Bundle. The Create Working/Protecting Bundle form opens. Repeat 2 and 3 to create the APS protection bundle.
11	To configure the administrative state of the APS working and protection bundles: Note: You must configure the End Point ID parameter on the APS PPP group before you change the working or protection bundle state. Use the following steps: Right-click on the working bundle object below the SC APS Bundle object in the navigation tree and choose Properties. The Multilink Bundle (Edit) form opens. Click on the States tab and configure the Administrative State parameter. Click OK. Right-click on the protection bundle object below the SC APS Bundle object in the navigation tree and choose Properties. The Multilink Bundle (Edit) form opens. Repeat 2 and 3 to configure the administrative state of the protection bundle.
12	Add members to the APS bundle. Use the following steps: Right-click on the SC APS Bundle icon in the navigation tree and choose Create Bundle Members. The Add Bundle Member form opens. Click Next to add DS0 channel groups to the bundle. The Select Channels form opens. Select a compatible channel from the list. Note: When initially adding bundle members, you must first add one channel group and then repeat the procedure to select up to seven additional channel groups. Only compatible channels are listed. If you want to configure and use a channel that is currently incompatible, you can click on the Back button, deselect the Show Only Compatible Channels parameter, click on the Next button, select the channel, click on the Properties button. The channel group with the lowest Port ID is the primary member for the bundle. The Encap Type of the primary member is used for all other members. When adding members to a bundle at a later time, the Encap Type must be the same as the primary member Encap Type for the member to be compatible. Click Finish. The Add Bundle Member form closes. Click Apply and then click Add. The Add Bundle Member form opens. Configure the Show Only Compatible Channels parameter and click Next. The Select Channels form opens. Select up to seven additional channels from the list. Click Finish.
13	Save your changes and close the form. End of steps
